My invention relates to railroad rolling stock and consists in a locomotive frame par ticularly adapted for an electric locomotive including motors connected to the driver axles of the locomotive, and more particularl to that type of an electric locomotive in whic there are a plurality of driver axles journaled in a frame of the rigid wheel base type.

As is well understood in the art, the len h of a ri 'd wheel base frame is limited ue to trac curvatures and the resulting 'disalinement of the successive wheels on one side of the frame when the vehicle is on the curved track. It is also well known in the art that the construction of a large electric locomotive including internal combustion engine', steam engine, or other engine structure, creates serious roblems in connection with the transverse racing of the sides of the frame because of the presence of the motors and their interference with transverse braces of the usual ty which ordinarily exte'nd down below the lvel of the to s of the pedestal openings in the frame. uch ordinary transom braces cannot be used without extending their wheel base to a length which would interfere with the proper negotiation of curves.

One of the main objects of my invention is to construct a locomotive frame having a rigid wheel base of minimum length mounted on a plurality of motor driven axles and to substantially brace laterally the pedestal forming side members of the frame and to embody in the lateral braces adequate supports for the ends of the motor housings not mounted on the axles.

Another object of my invention is to associate in such a rigid wheel base driving assembly a foundation for a wer plant of suilicient depth to provide a egree of rigidity which will prevent distortion of the mechanical elements comprising the power plant.

It vis an additional object of my invention to provide a frame having the characteristics mentioned with la minimum amount of Inaterial and labor. Preferably, I desire to form the frame of arts integrally associated with each other, t erehy eliminating the disad- 1989. Serial No. $88,888.

vantages of riveted or bolted structures; this feature however is not essential to the broader aspects of my invention.

An additional object of my invention is to provide a frame having a main portion ef relatively deep and heavy sections to form an adequate and rigid support for the engine and generator together with relatively light extensions for carryin the cah strucn ture where it extends beyon the engine and generator and for carrying other equipment.

Another object of my invention is to utiliae the engine and generator carryin sills as conduits for air currents and for pipin re spectively, and t0 provide the air conduit with extensions for delivering the air to the motor housings independently'of other trame elements or additional parts.

A frame of the ty referred to is mounted upon driver axle bixes located olfitsniche of the Wheel gauge (in order te provide room for the motors locatedbetween the wheel@ and the sills for supporting the engine, generator, etc., should not be s aced'nearly se far apart as the pedestal-forming portions of the frame. It is a further object of my inven tion to combine these two frame elements with each' other so that each forms in eect a vertical extension of the other thereby in creasing the rigidity of the frame.

It is also my desire to include transome extending transversely of the frame and eracing the engine supporting siils and the side members substantially throughout the depth of the side members but without interfering with the motors,'driver axles and other running gear. Preferably, these transoms will also serve to support one end of each motor housing.

Another obiect of. my invention is to in clude in a 'frame of the type described pertions of buiiing devices for transmitting buil ing thrusts to the main portion ci the Theseand other detailed objects which will be'referred to in the body of my specification are attained hy the construction illustrated in the accompanying drawings in which;

Figures. 7, 9, 10, 11, 15, 16, 2o, 29, 3o and 36 are longitudinal vertical sections taken on the corresponding section lines of Figure 1;

Figures 32 and 33 are horizontal sections teken on lines 32--32 and 33-33 of Figure 3;

Figure 37 is a vertical transverse section taken on line 37-37 of Figure 2.

The frame is mounted on the driver axles A by means of the usual journal boxes (not shown) which are received in the pedestal portions 1 of the side members 2 of the frame. These side members comprise an inner Wall 3 and an outer wall 4 the same being connected at intervals by horizontal. elements 5, 6,7, and 8 (Figs. 13, 14, 19, 22, 23, and 24) forming either a ill-shaped or a box shaped cross section substantially throughout the length of the side member.

The inner walls of the side members extend upwardly above the top of the outer walls 4 and form the outer walls of longitudinal sills 9 and 19' each having an inner wall 10 and having a top wall 11 provided with a pad to be machined for mounting the locomotive engine and generator (not shown). This sill also has a bottom wall 12 whereby a box shaped cross section isprovided from end to end of the sill and on one side of the frame the sill 9 will be utilized as an air conduit for leading a stream of air from a suitable blower (not shown) to the axle driving motors (not shown). To facilitate molding and casting, the sill 9 is shown provided with a plurality of openings 13 and these openings will be closed by applying suitable plates such as 14 (see Figures 18, 23 and 24) The opposite sill 19 may be utilized as a container for iping or similar equipment and it will not e necessary to close the openings therein if the sill is used for this purpose.

The sills 9 and 19 are located a substantial distance above the level of the side members 2 and are nearer to the centerline of the frame throughout most of their length but near the front end (left hand end or Figure 1) these sills diverge as indicated at G to provide a wider space between them to clear the generator housing which is substantially wider than the internal combustion engine which will be mounted on the rear portion of the sills.

The opposite ends of the sills are provided with suitable pads 45 and 46 on which a. water heater and an air blower may be mounted.

with each other and transom 16 also connects with the ends of side members 2. 'lfhe opposite end portions of side members 2 extend diagonally inward from the forward pedestals and merge with the outer walls of sills 9 and 19 at points adjacent to but spaced from transom 15.

Each transom 15 and 16 is of boi: shaped cross section from end to end and is deeper than the side members 2 and projects laterally from the frame beyond sills 9 and 19 and the side members 2. These projecting portions of the transoms provide suitable elements whereby the frame may be bodily lifted by means of crane slings or jacks. The transoms form braces for the side members and engine sills substantially throughout the depth of the side members and they are so shaped that they are adapted to absorb lateral and longitudinal forces applied to the frame.

Transom 15 mounts a center plate 17 adapt ed to engage a corresponding center plate on an engine truck the wheels of which are indicated at 18. Transom 16 mounts a similar element 20 (Fig. 20) comprising the radius bar fulcrums of the two wheel trailer truck the wheels of which are indicated 2l. Preferably these elements 17 and 20 are integral with the transoms.

Located between the main transoms 15 and 16 are intermediate transoms 22, 23, 24 and 25, each having spaced walls extending trans versely of the frame and merging with sills 9 and 19 and side members 2. The forward wall of each transom is deeper than the reu r wall and the ends of the deeper portions out the forward walls extend diagonally of the frame below the rear walls of the transoms and merge with the side members at points locates the end portions of the transom inter" mediate the driver wheels so that there is no interference with the langes or" the latter. The transoms comprise cross sect-ions ot shape or box shape oi substantial width and depth and they brace the side members at points adjacent to the level ot the pedestal openings. On transoms 22 and 24 the diagonal end portions include boi; sections and in transom 24. the portions merging with the side members are Wider than theintermediato "l part ofthe transom, as best shown at 24 (Fig. 3). Transom 24'has its intermediate portion recessed upwardly to provide better clearance conditions (Figs. 22 and 24).

Each transom 22, 23, 24 and 25 is adapted to mount between its front and rear walls a spring unit of the ordinary type for supportingk a motor housing nose. The pads 40 willi] enga e the upper bar of the unit and the ape r ture bosses 41 serve to receive removab n ins for supporting the lower bar of the unit.vl

ach transom has an opening '42 through which a hanger carried by the spring unit may extend downwardly to engage the motor noses.

Webs 43 extending transversely of the transom walls serve as stops to limit lateral movement of the spring units, and lugs 39 form safety brackets to prevent dropping of the motor in the event of failure of the support.

Extending inwardly from sill 9 at points spaced from the intermediate transoms are a series of branches 9 adapted to lead air from the main conduit to the individual motors. Each branch is braced from the adjacent transom by an element 26 but the branch does not form a part of the transom. Each branch terminates in a downwardly facing outlet adapted to connect to a corresponding' opening in the motor housing.

The walls 3, common to side members 2 and sills 9 and 19, extend beyond transoms 15 and 16 for a substantial distance as'indicated at 26 and are connected at their ends by endl sills 27 and 28. Draft sills 29 also connect the transoms with the end sills and carry cross members 30 each comprising upper and lower portions forming pockets 31 for the draw bars and having seats 32 for the draw bar pins.

IIhre end sill 27 is provided with a radial butler beam 33 adapted to receive buiiing forces and transmit them through the draft sills to the main portion of the frame. End sill 28'forms housing or bearing elements 28l for the usual stems (not shown) carrying a butiing plate; This end sill has lower faces 84 adapted to mount bearing plates for the ordinary rocker bearings (not shown).

Brake ulcrums 34 and 35 are provided at points spaced from the adjacent pedestals and are mounted on suitable bracket arms 36, extending from the pedestal legs longitudinally of the frame and on arms 37 extending downwardly from the side members 2 and merging with the adjacent transom.

F langes 38 4and brackets 47' projecting outwardly from the side members 2, and the main transoms 15 and 16 and the sills 9 and 19 and their longitudinal extensions 26, 29 and the endV sills all co-operate to form a. deck for mounting a cab (not shown) which encloses the power [plant and operating coni- V` tension or reinforcement of the other, giving4 an unusuallydeep side girder for the frame between the main transoms.

The rigidity of the frame as describes above is maintainedor increased by the deep transom structures 22. '23, 24 and 25,` each orting the engine ers mounted on the of which is united with the side members at adequate transoms of ordinary construction which, as pointed out above, would require greater distances between the pedestals inV order to clear the motors and driver wheels.

Many of the members have their cross sections changed substantially in shape and area and the hollow sections which-,I havev used freely may be of different proportions or rounded instead of rectangular and other details of the construction may differ from that shown without varying the principles embodied in the frame. I haveillustrated a one piece casting including all of the elements ot the frame but many of theelements lmay be eliminated without affecting the general design and others may be secured to the frame body by rivets or bolts.- I consider the welding of separately, formed parts into an integral whole as completely within the spirit of luy-invention and contemplate the exclu.
